Unreleased 

migrate build & dependency management to Poetry: replace setup.py and requirements*.txt with a single pyproject.toml (PEP 621) plus committed poetry.lock and test/linter/docs/dev dependency groups; CI now builds, tests and publishes via Poetry (with .venv caching) (#48
fix parsing of multi-select (tags) custom attributes when the Personio API returns them as a JSON-encoded list string (e.g. '["A","B"]') instead of a comma-separated string (#48
drop support for Python 3.7-3.9 (all end-of-life); personio-py now requires Python >= 3.10 (#46
raise the requests requirement to a modern version (#46
modernize the development tooling: replace flake8 with ruff, add pip-audit and bandit to pre-commit, bump all pre-commit hooks, and migrate the Sphinx docs to myst-parser (#46
send auth credentials in the request body instead of the query string, as required by the Personio API security update effective 2025-12-01 (query-string credentials return a 403 Forbidden from that date on) (#45
fix PersonioError: Missing Authorization Header in response for the attendances and projects endpoints, which do not return a rotating auth token (disable auth rotation for those requests, consistent with the existing image endpoints)
fix AttributeError in to_dict() when an object field is returned empty ("" or []) instead of null by the Personio API; such empty object fields are now deserialized to None (#47
add support for providing a custom requests.Session in client (#39

add new fields: ‘updated_at’ and ‘category’ to the Absence and AbsenceType classes (#26)
Upgrade Sphinx and fix CI job (#27)

add support for new API functions: get_absences, get_absence_types, create_absence, delete_absence, get_attendances (thanks philipflohr!)
add support for paginated API requests (required for attendances & absences)
make from_dict() and to_dict() behave consistently
meta: improve CI builds & tests, better pre-commit hooks
lots of mock tests & documentation
